Lesson Worksheet: Volume of Sound Science

In this worksheet, we will practice describing the link between the strength of vibrations and the volume of a sound.

Q1:

Select the statement that shows the link between the strength of vibrations and the volume of sound.

• AThe weaker the vibrations, the louder the sound.
• BThe weaker the vibrations, the quieter the sound.
• CThe stronger the vibrations, the quieter the sound.

Q2:

Fill in the blank: Strong vibrations have energy than weaker vibrations, so they make louder sounds.

• Amore

• AThe sound is quiet because the plane is far away.
• BPlane engines make quiet sounds.
• CPlane engines make a sound with weak vibrations.

Q5:

Mona plays the trumpet. The harder Mona blows the trumpet, the louder the sound.

When Mona blows harder, what happens to the strength of the air vibrations inside the trumpet?

• AThey decrease.
• BThey increase.
• CThey stay the same.

Q6:

David, Jennifer, and Liam investigate how the distance from the source of a sound affects the volume. Jennifer will ring a bell. David will walk 150 m away from Jennifer. Every 50 m, he will record the volume of the sound.

Here are their predictions:

Here are their results:

 Distance between David and Jennifer (m) Volume of the Sound David Hears 1 50 100 150 Loud Quiet Very quiet No sound

Whose prediction was correct?

• ALiam
• BDavid
• CJennifer

Q7:

Jackson, Hannah, and Daniel are investigating how the distance from the source of a sound affects the volume. Hannah will ring a bell. Jackson will walk 150 m away from Hannah. Every 50 m, he will record the volume of the sound. Here are their predictions.

Here are their results.

 Distance between Jackson and Hannah (m) Volume of the Sound Jackson Hears 1 50 100 150 Loud Quiet Very quiet No sound

Whose prediction was correct?

• AHannah
• BJackson
• CDaniel

Select the statement that is true.

• AThe sound is quiet because the plane is far away.
• BThe plane’s engine makes a sound with weak vibrations.
• CThe plane’s engine makes quiet sounds.

Q10:
